About Block Bloom

Block Bloom is a tiling puzzle: you have a board and a tray of polyomino pieces, and the board must be covered exactly. Not mostly, not with a gap in the corner — exactly. Every square filled, every piece used.

That exactness is what separates it from block-dropping games it superficially resembles. There is no scoring by degrees and no partial credit. A piece either belongs somewhere or it does not, and the puzzle has a solution which you are looking for rather than a high score you are accumulating.

The pieces are the familiar polyomino shapes — L bends, T shapes, squares, long bars — and the useful habit is to place the awkward ones first. An L with a corner sticking out has very few homes on a partly-filled board, while a two-by-two square will fit almost anywhere. Players who place the easy pieces first tend to end up holding an L with nowhere to put it.

Corners and edges are where most solutions start, because those cells are constrained by the board itself and often only one piece shape can serve them. Working inward from the boundary turns a large open board into a much smaller problem surprisingly quickly.

There is a move budget per level, so it is not purely trial and error, and completing a board reveals a piece of hidden artwork underneath. Forty levels, with hints and boosters for the ones that refuse to yield. Drag a piece from the tray and the preview turns green when it fits; tap a placed piece or press Undo to take it back.

Frequently asked questions

Do I have to fill the board completely?

Yes. Each board must be tiled exactly, with every square covered and no gaps left over. A solution either works completely or it does not.

How do I know if a piece fits?

Drag the piece over the board and the preview turns green when the placement is valid. If it does not turn green, the piece either overlaps something or leaves the board.

Any advice for harder levels?

Place the awkwardly-shaped pieces first, since they have the fewest valid positions, and work from the corners and edges inward — boundary cells are the most constrained and often accept only one shape. Leaving an L-shaped piece until last is how most attempts fail.

How many levels are there?

There are 40 levels, each with a move budget. Hints and boosters are available, and completing a board reveals a piece of hidden artwork.
